Description

The invention relates to a roof of a tarpaulin structure for a commercial vehicle, in particular trucks, trailers or semitrailers, with at least one stile structure, at least one stanchion scooter for moving a stanchion connected to the sprocket in the direction of the spar structure and at least one tarpaulin scooter for moving a connected to the tarpaulin roller Tarpaulin in the direction of the spar structure, wherein the Runge roller at least one rolling on a Rungelauffläche the spar structure in the longitudinal direction of the spar structure and the pulley substantially in the direction of gravity supporting stanchion roller, said tarpaulin rolling at least one on a tarpaulin surface of the spar structure in the longitudinal direction of the spar structure and the tarpaulin roller having substantially in the direction of gravity supporting tarpaulin roller and wherein the tarpaulin roller at least one plane roller substantially transverse to the direction of gravity at least one Pl Anenstützfläche the spar structure has supporting tarpaulin support. In addition, the invention relates to a tarpaulin structure for a commercial vehicle, in particular trucks, trailers or semitrailers, with such a roof, with at least one Runge scooter on the roof guided stanchion and with at least one guided over at least one tarpaulin on the roof tarpaulin.

Commercial vehicles of the type mentioned, for example in the form of trucks, trailers and semitrailers, are particularly intended for the transport of goods, preferably general cargo, on public roads. For this purpose, the commercial vehicles on different types of structures, which serve to accommodate the goods to be transported in a hold. Thus, for example, box bodies with solid side walls and a fixed roof are known which surround the cargo space. Since the box bodies are closed, box bodies are particularly for the transport of moisture-sensitive and / or temperature-sensitive goods, so for example suitable for so-called dry transport and / or refrigerated transport.

In addition to box bodies also known as tarpaulin structures are known in which the side walls and the roof are closed by at least one tarp. The end wall is usually formed in tarpaulin structures as a solid wall, while the rear wall is formed regularly by two gull-wing doors to load the cargo space from behind, if necessary. If a tarpaulin can be moved along the side wall, one also speaks of so-called curtainsiders.

The roof of tarpaulin structures typically has laterally arranged spar structures in the form of longitudinal bars, which are connected to form a frame structure transverse to the commercial vehicle via braces. The frame structure then carries the roof closing the tarpaulin. For this purpose, the spar structures are carried in the closed state of the tarpaulin structure of stanchions, which are arranged at the edge of the hold and there releasably connected to the edge of the loading floor. The stakes then extend approximately perpendicular to the loading floor upwards in the direction of the roof of the tarpaulin structure. Depending on where the corner stanchions are provided, they are so-called central stanchions or corner stanchions. Corner stanchions are provided at the corners of the cargo space or the commercial vehicle, while central stanchions can be provided laterally on the commercial vehicle between the corner stanchions. In particular, in semitrailers are regularly provided on each side 3 to 4 Mittelrungen between the Eckrungen.

In order to simplify the loading and / or unloading of tarpaulin structures, the central stanchions can be detached on their underside from the floor of the tarpaulin structure and moved forwards or backwards in the longitudinal direction of the stile structure. For this purpose, the stanchions are connected to the spar structure via stanchion rollers, which can be held in the stile structure and displaced via stanchion rollers on stanchion running surfaces along the stile structure. Moving the stanchions This can be done with the sliding of a tarpaulin of the tarpaulin or separately. The side tarpaulin is connected for the purpose of pushing with tarpaulin rollers, which are connected via tarpaulin rollers with the spar structure. The tarp roller are held in the spar structure and can be moved on tarpaulin rollers on tarpaulin treads along the spar structure. In order to support the tarpaulin roller essentially transversely to the direction of gravity on the spar structure, the spar structure has at least one tarpaulin support surface and the tarpaulin roller at least one tarpaulin support which is supported substantially transversely to the direction of gravity on the tarpaulin support surface. In order to guide the tarpaulin rollers when moving the side tarpaulin along the spar structure, the tarpaulin support surface may extend in the longitudinal direction of the spar structure and thus serve for supporting the tarpaulin roller, in particular the tarpaulin support, when the tarpaulin is displaced along the longitudinal extension of the spar structure. Alternatively, however, the spar structure can also have a tarpaulin guide surface on which a tarpaulin guide roller can roll. If the tarpaulin structure does not have longitudinally displaceable side tarpaulins, the stanchions for loading and unloading can nevertheless be displaced along the spar structure. In addition, the spar structure can be used as needed for carrying and moving a so-called sliding roof, in which the brackets are fixed slidably on Spriegelroller to the spar structure.

For the different designs and requirements of the described tarpaulin structures are typically many different spar structures, stanchion scooters and tarpaulins available. By combining them, suitable roofs for tarpaulin structures can always be provided. However, the corresponding diversity of the roofs also leads to high production and storage costs.

Therefore, the present invention has the object, the roof and the tarpaulin structure each of the aforementioned and previously described in more detail type and further develop that the production of different roofs can be made easier and cheaper.

This object is achieved in a roof according to the preamble of claim 1, characterized in that the upper edge of the at least one Runge roller is arranged on or above a plane extending through the tarpaulin support and parallel to the roof level.

The above object is also achieved in a tarpaulin structure according to the preamble of claim 15, characterized in that the roof is designed according to one of claims 1 to 14.

By arranging the at least one tarpaulin support relative to the at least one idler pulley in such a manner that the upper edge of the idler pulley is arranged at least at the level of the tarpaulin support, a compact and preferred geometry of the spar structure becomes possible. The at least one tarpaulin support and the at least one idler pulley are thus preferably provided at least partially overlapping each other. With regard to the tarpaulin support, it is particularly important for the part which is supported on the spar structure and less for the connection of the tarpaulin support to the rest of the tarpaulin roller. If necessary, therefore, the contact surface of the tarpaulin support on the spar structure is not arranged higher than the upper edge of at least one Rungelaufrolle. In other words, the tarpaulin support or the contact surface of the tarpaulin support can be arranged on the spar structure next to or at the level of the idler pulley. As a tarpaulin support is for example a projection, a nose or a rib in question, which may be required formed of a plastic and having a contact surface for engagement with the tarpaulin support surface.

In the case of several stanchion rollers of the at least one stanchion roller, the upper edges of which are arranged at different heights relative to the roof in the spar structure, the at least one staking roller may be the stanchion roller with the uppermost edge. Alternatively or additionally, in Case of several tarpaulin supports of the at least one tarpaulin roller whose lower edges are arranged at different heights relative to the roof in the spar structure, are understood by the at least one tarpaulin support the tarpaulin support with the lowest arranged lower edge.

The corresponding spar structure also makes it possible to meet various requirements for tarpaulin structures with a single spar structure. For example, a large loading width in the cargo space between the side spar structures and at the same time a high loading opening between the loading floor and the spar structure of the tarpaulin structure can be provided. This is possible, for example, as a result of the arrangement of the at least one tarpaulin support and the at least one idler pulley making the spar structure narrow and yet not very high. Nevertheless, the spar structure provides great functionality and variability, making the spar structure suitable for a variety of applications.

A plane extending parallel to the roof in the sense of the invention can be understood as meaning a plane which is parallel to a main plane of the roof. The roof must therefore have no flat top or bottom, so that a plane can be defined as parallel to the roof. In this context, it does not depend on an exact mathematical definition or determination of the level of the roof. Preferably, the roof is considered to be parallel to a loading floor of the tarpaulin structure, wherein the loading floor of the tarpaulin structure regularly formed flat but can also deviate from it, such as when so-called Coilmulden or the like are provided in the bottom of the tarpaulin structure. Alternatively or additionally, the plane of the roof and thus a plane parallel thereto transverse to the spar structure can be understood as a horizontal plane, such as when the commercial vehicle is in a conventional manner on a horizontal plane. The above definitions of the plane of the roof or a plane parallel to the roof can, if necessary, be regarded as synonymous.

In a first particularly preferred embodiment of the roof, the at least one tarpaulin support of the tarpaulin roller as a tarpaulin guide roller and the tarpaulin support surface of the spar structure are formed as a tarpaulin guide surface. Then, the tarpaulin or the tarpaulin rollers when opening the tarpaulin can be easily and precisely performed on the spar structure. The at least one tarpaulin guide roller can roll on the at least one tarpaulin guide surface and thereby guided substantially transversely to the direction of gravity on the tarpaulin guide surface. Then, the at least one tarpaulin guide roller is arranged such that the upper edge of the at least one idler pulley is disposed on or above a plane passing through the at least one tarpaulin guide roller and parallel to the roof to further benefit from the advantages described above.

Alternatively or additionally, a plane passing through the tarpaulin support and / or tarpaulin guide roller of the at least one tarpaulin roller and parallel to the roof intersects the at least one idler pulley of the at least one pulley between the upper edge and the lower edge of the idler pulley. The at least one Runge roller is thus arranged at the level, in particular next to the tarpaulin support and / or tarpaulin guide roller and vice versa. This embodiment of the spar structure has proved to be particularly space-saving and advantageous with respect to the geometry of the spar structure. The arrangement of the at least one idler pulley further upstream relative to the at least one tarpaulin support and / or tarpaulin guide roller or the arrangement of the at least one tarpaulin support and / or tarpaulin roller beneath the at least one idler pulley can result in geometrical and structural compromises which dictate the geometry and dimensions of the Holm structure can adversely affect. Also in this case, it is true that in the case of several stub rollers of the at least one stanchion roller, the upper edges of which are provided at different heights relative to the roof in the spar structure, the at least one stanchion roller may be the stanchion roller with the uppermost edge. Alternatively or additionally, in the case of several tarpaulin supports and / or tarpaulin guide rollers of the at least one Planar scooter whose lower edges are arranged at different heights relative to the roof in the spar structure, are understood by the at least one tarpaulin support and / or tarpaulin guide the tarpaulin support and / or tarpaulin guide roller with the lowest arranged lower edge.

For structural and geometric reasons, it is also preferred if the at least one tarpaulin support and / or tarpaulin guide roller of the at least one tarpaulin roller is arranged below the at least one tarpaulin roller of the tarpaulin roller. Corresponding tarpaulins are also easy and reliable to operate.

Alternatively or additionally, the at least one tarp roller may be pivotably provided with respect to the spar structure such that the at least one tarpaulin support and / or tarpaulin guide roller lifts from the associated tarpaulin support surface and / or tarpaulin guide surface and a distance between the at least one tarpaulin support and / or tarpaulin guide roller on the one hand and the associated with the tarpaulin support surface and / or tarpaulin guide surface on the other. In this way, a simple and reliable operation of the sliding tarpaulin of the tarpaulin structure is achieved without thereby disproportionate disadvantages in terms of structure and geometry of the spar structure must be taken into account. This is even more true if the tarpaulin roller, in particular the tarpaulin support surface and / or tarpaulin guide roller laterally outwardly relative to the spar structure or on the tarpaulin structure is formed pivotable.

In order for the at least one tarp roller to be held stably on the spar structure, even if the side tarpaulin of the tarpaulin structure is displaced, it makes sense if at least two tarpaulin rollers are provided on at least one tarp roller. In order that this can be realized in a space-saving manner, it is further preferred if the at least two tarpaulin rollers of the at least one tarp roller are provided on a common tarpaulin surface of the spar structure running off.

For safe and reliable handling of the at least one stanchion of the tarpaulin structure, it makes sense if the at least one stub roller has a stanchion carriage and at least one stanchion roller fixed to the stanchion carriage. The stanchion carriage may then, if necessary, provide the necessary strength and rigidity and be connected to the actual stanchion. In this case, a space-saving and geometrically advantageous embodiment of the spar structure is achieved if the at least one stanchion roller is provided on one side of the at least one sprocket roller adjacent portion of the Rungsschlittens, which points away from the at least one tarpaulin support and / or tarpaulin guide roller. In other words, the at least one idler pulley is provided on the side of the stanchion carriage or the stanchion carriage section facing away from the at least one tarpaulin support and / or tarpaulin guide roller and adjacent to the at least one idler pulley. Preferably, this is realized in such a way that the Rungenschlitten seen transversely to the spar structure and, if necessary, in a plane between the at least one Runge roller and the at least one tarpaulin support and / or tarpaulin guide roller is arranged.

Alternatively or additionally, the at least one pulley roller may have at least two stanchion rollers fixed to the stanchion carriage. As a result, the stanchion carriage and thus the stanchion scooter can be secured against tilting or at least held more stably on the stile structure. A particularly space-saving and geometrically advantageous embodiment of the spar structure provides that the at least two Rungelaufrollen seen in the longitudinal direction of the spar structure are fixed on the same side of the adjacent to the at least one sprocket roller Rungenschlittenabschnitts. The roller scooter including the sprocket rollers can be made quite narrow, what the required width of the spar structure for receiving the Runge scooter can benefit. In other words, it is preferable to dispense with idler pulleys on both or opposite sides of the stanchion carriage or the stanchion carriage section associated with the idler idlers, so as to achieve geometrical and structural advantages.

Alternatively or additionally, it offers from a structural and geometric point of view, if at least two Rungelaufrollen the at least one Runge scooter are provided running on a common Runge tread of the spar structure. It is particularly expedient if all Runge rollers of at least one Runge scooter are rolling on a common Runge tread. In this way it is sufficient to provide a single Runge tread in the spar structure, which can save space.

The spar structure can be made particularly narrow, without this having to lead to an undesirable impairment of the length of the spar structure when the at least one tarpaulin support surface and / or tarpaulin guide surface is at least partially offset inwardly from a plane provided on the outside of the spar structure. Such an offset is understood in particular to mean one which is directed in the direction of the at least one idler pulley. Alternatively or additionally, however, the offset can also be provided in the direction of the interior of the spar structure facing the loading space of the tarpaulin structure.

For a suitable guidance of the stanchion roller in a space-saving manner, the at least one stanchion running surface of the spar structure and / or the at least one tarpaulin rolling surface of the spar structure can have a curved shape in cross-section of the spar structure. If the curvature is approximately in the form of an upwardly open U, lateral slippage of the at least one idler roller and / or the at least one tarp roller can also be avoided. Alternatively or additionally, for an easy and exact displacement of the side tarpaulin and / or the at least one stanchion, the at least one Runge roller and / or the at least one tarpaulin roller have a curved tread. In this case, a curvature is particularly expedient, in which the corresponding tread arched centrally outward and / or is formed in cross-section approximately U-shaped.

With regard to the guidance of the tarpaulin roller and the reliable derivation of the forces that occur, the at least one tarpaulin support surface and / or tarpaulin guide surface of the spar structure may have a planar shape and / or the tarpaulin support and / or tarpaulin guide roller may have a planar contact surface and / or tread.

A reliable and space-saving connection of the stanchions can be achieved if the stanchion slide of the at least one stanchion roller extends through a downwardly open and extending in the longitudinal direction of the spar structure slot in the spar structure inside. In the corresponding area of the Rungenschlitten is therefore preferably plate-shaped. In addition, structural and geometric advantages can be achieved if the stanchion slide section adjoining the at least one stanchion roller is arranged laterally next to the at least one stanchion running surface in the longitudinal direction of the stile structure. Alternatively or additionally, a contact surface for at least one mounting profile inserted at at least one end of the spar structure may also be provided on the side of the slot facing the tarpaulin roller. About the at least one mounting profile, the spar structure can then be easily and safely connected to the front wall and / or the rear wall of the tarpaulin structure. For this purpose, the at least one contact surface is aligned at least predominantly transversely to the direction of gravity. Thus, the spar structure can be screwed, for example, from the bottom of the spar structure with the at least one mounting profile.

For connecting the spar structure with an end wall and / or a rear wall via a corresponding mounting profile may alternatively or additionally in preferred Way below the tarpaulin support surface and / or the tarpaulin guide surface, a receptacle for receiving the at least one mounting profile may be provided, which can be inserted from one end of the spar structure in the spar structure. The receptacle is preferably designed to be open to the side facing away from the tarpaulin roller side of the spar structure. So a wider mounting profile can be provided, which can accommodate greater assembly forces. Thus, the inserted into the spar structure mounting profile simple, such as cuboid, can be formed, the recording in cross-section, if necessary, approximately U-shaped. In order to provide a wide mounting profile and to transmit such high assembly forces, the recording for the mounting profile preferably extends at least up to a defined by the tarpaulin support surface and / or tarpaulin guide surface and perpendicular to the roof plane in the direction of the tarpaulin roller facing side of the spar structure. The mounting profile can be supported, if necessary, both in the receptacle and at or adjacent to the Runge tread. The at least two contact surfaces between the mounting profile and the spar structure can be separated from each other by the provided on the underside of the spar structure slot. In principle, the receiving space for the at least one stake roller in the spar structure below the tarpaulin support surface and / or the tarpaulin guide surface can be wider than in the area of the tarpaulin support surface and / or the tarpaulin guide surface.

In order to avoid wedging of the stanchion roller and / or damage to the at least one stanchion roller, the stanchion carriage may be pivotally connected to the stanchion. Thus, it is possible, if necessary, that the stanchion can be pivoted relative to the Rungenschlitten about an axis parallel to the longitudinal extent of the spar structure. The stanchion can be pivoted in this direction, in particular when setting and releasing the stanchion on the loading floor of the tarpaulin structure and / or when displacing the stanchions along the stile structure. The appropriate handling of Runge is not hindered by the pivotal connection to the Rungenschlitten. At the same time, the stanchion scooter when pivoting the stanchion in at least substantially unchanged orientation be held in the Holstruktur. The corresponding pivotability can be provided by a pivot joint between the pulley and the stanchion. However, for the sake of simplicity and longevity, it is preferred that the stanchion scooter be connected to the stanchion with enough play to enable the stance to pivot.

Thus, the at least one Runge roller can be safely guided and secured against excessive lifting of the Runge tread, the spar structure preferably has at least one extending in the longitudinal direction of the spar structure supporting surface for rolling the at least one Rungelaufrolle when the at least one Rungelaufrolle in one of the Runge tread is off position and the associated Runge is moved along the spar structure.

The flexibility for the use of the spar structure can be increased if at least one Spriegelroller is provided for moving a bow along the spar structure. In this case, it is functional if the sprag roller has at least one antiroll roller rolling on a crossbeam running surface of the spar structure in the longitudinal direction of the spar structure and carrying the sprocket roller essentially in the direction of gravity. Thus, ultimately, the bow and the tarpaulin carried by the bows can be securely supported against the spar structure or supported by the spar structure. If, alternatively or additionally, at least one Spriegelstützrolle rolling on a support surface of the spar structure in the longitudinal direction of the spar structure and the pulley substantially against the direction of gravity against lifting the Spriegelrollers is provided, the bow and the tarpaulin held by the bows can be securely held on the spar structure , Regardless, for reliable and easy guidance of the bow when sliding and / or closing the sliding roof, at least one Spriegelführungsrolle leading to the Spriegelroller substantially transversely to the direction of gravity, rolling on a tarpaulin guide surface of the spar structure have.

In order to provide the functionality of a sliding roof and also a versatile spar structure, it is advisable, at least one Spriegellaufrolle the at least one Spriegelrollers further inside with respect to the at least one Spriegelstützrolle the at least one Spriegelrollers and if necessary complement the Spriegelführungsrolle the at least one Spriegelrollers to provide in the transverse direction to the spar structure between the Spriegellaufrolle and the Spriegelstützrolle.

the detail of the roof according to Fig. 2B at an end of the spar structure connected to the rear wall.

In the Fig. 1 a drawn by a tractor Z commercial vehicle N is shown in the form of a semi-trailer. The commercial vehicle N has a tarpaulin structure 1 in the form of a curtainsider. The tarpaulin structure 1 has a tarpaulin 2 on the roof 3 and in each case a side tarpaulin 4 on the two side walls 5 of the tarpaulin structure 1. The two side panels 4 on the side walls 5 can be moved forward or backward to release the access to the space enclosed by the tarpaulin structure 1 loading space 6. Another access to the hold 6 can through the Wing doors 7 of the rear wall 8 done. The side tarpaulin 4 on the front side wall 5 of the tarpaulin structure 1 is partially pushed so that a stanchion 9 can be seen, which is connected on the one hand to the loading floor 10 of the tarpaulin structure 1 and on the other hand to a longitudinally extending spar structure 11 in the form of a longitudinal spar. The stanchion 9 can be separated from the loading floor 10 of the tarpaulin structure 1 for loading and unloading and moved along the spar structure 11 to the front or to the rear. In addition to in the Fig. 1 Runge shown are still other similar, hidden by the front side tarp 4 stanchions 9 are provided. The tarpaulin 2 on the roof 3 of the tarpaulin structure 1 can also be pushed forward for loading and unloading. The tarpaulin 2 on the roof 3 is therefore part of a sliding roof 12, which is also held on the side of the spar structure 11.

In the Fig. 2A-B a detail of the roof 3 is shown in a sectional view through the spar structure 11. The same detail is also in the Fig. 3 shown in a side view from the outside of the tarpaulin structure 1, but the tarpaulin 2 of the roof 3 has been omitted for better clarity sake. The Fig. 2A-B and the Fig. 3 will be described together afterwards.

The spar structure 11 is L-shaped with an upper leg 13 at least substantially parallel to the roof 3 and a lateral leg 14 at least substantially perpendicular to the roof 3. At the bottom of the spar structure 11, a slot 15 is provided, which extends in the longitudinal direction Holmstruktur 11 extends and the connection of the spar structure 11 associated stanchions 9 is used. The stanchions 9 are connected to stanchion rollers 16 which each comprise a stanchion carriage 17 and stanchion rollers 18. The stanchion carriage 17 extends through the slot 15 into the stile structure 11, into a receiving space 19 for the stanchion rollers 18.

The stanchion rollers 18 are fixed to the stanchion carriage 17 and seen in the longitudinal direction of the spar structure 11 on a common side of the stanchion slide 17 and the adjacent to the stanchion rollers 18, in the Holmstruktur 11 received Rungenschlittenabschnitts 20 arranged. The actual stanchion 9 is in the state connected to the loading floor 10 with a collar 21, preferably frictionally, on the underside of the spar structure 11 at. In addition, the actual stanchion 9 can slide down in the released state of the loading floor 10 with the fixed to the stanchion 17 collar 21 up to 22 stops that support the collar 21 then. Between the Rungenschlitten 17 and the openings 23 for performing the Rungenschlittens 17 in the collar 21 a lot of game is provided so that the stanchion 9 can be pivoted outwards, without causing the Rungenschlitten 17 is deflected in the same direction or the Rungelaufrollen 18 in the Do not block or pinch receptacle 19 for stanchion rollers 18. The stanchion rollers 18 are supported for holding the stanchion roller 16, in particular in the released from the loading floor 10 state on a Rungelauffläche 24 on which the Rungelaufrollen 18 roll for moving the Runge roller 16 together with the Runge 9 in the direction of the spar structure 11. Above the stanchion rollers 18 is a support surface 25 for unrolling the at least one stanchion rollers 18 in a position raised from the Runge tread 24 position. The support surface 25 extends in the longitudinal direction of the spar structure 11 and represents in the illustrated and so far preferred spar structure 11 is a part of the receiving space 19 for the stanchion rollers 18.

In addition to the stanchion 9, the side tarpaulin 4 is shown in a partially open position. The side tarpaulin 4 is fixed to a series of tarpaulin rollers 26, which have a tarpaulin carriage 27 and tarpaulin rollers 28, which are received in a receiving space 29 for the tarpaulin rollers 28. The tarpaulin rollers 28 are supported by a tarpaulin surface 30 along which the tarpaulin rollers 28 are displaced when rolling the side tarpaulin 4 and roll. Like the stanchion rollers 18, the tarpaulin rollers 28 are arranged one behind the other in the longitudinal direction of the stile structure 11 and of a similar design. In addition, the tarpaulin rollers 28 as well as the stanchion rollers 18 curved and in the center outwardly curved treads. The Runge tread 24 and the tarpaulin surface 30 have corresponding thereto an approximately U-shaped curved, upwards open shape. Above and adjacent to the tarpaulin rollers 28, a support surface 31 is provided which limits the lifting of the tarpaulin rollers 28 upwards. When moving the side tarpaulin 4, the tarpaulin roller 26 can be pivoted outward about an axis in the direction indicated by the arrow S, which extends through the connecting regions between the tarpaulin rollers 28 and the tarpaulin surface 30. At a maximum pivot angle, the tarpaulin rollers 28 come into abutment against an inner stop 32, which prevents further pivoting of the tarpaulin roller 26 to the outside. The pivoting back of the tarpaulin roller 26 in the direction of the starting position is limited when reaching the starting position by the investment of a tarpaulin guide roller 33 on a tarpaulin guide surface 34. The tarpaulin roller 26 can be guided during the displacement of the side tarpaulin 4 along the spar structure 11 by the unrolling of the tarpaulin guide roller 33 on the tarpaulin guide surface 34 of the spar structure 11.

In the illustrated and so far preferred roof 3, the tarpaulin guide roller 33 is disposed in the starting position at the level of the idler pulleys 28. A plane E1 parallel to the roof 3 at the level of the upper edges of the Runge pulleys 28 is disposed above the tarpaulin guide roller 33, while a plane E2 is arranged parallel to the roof 3 at the level of the lower edges of the Runge pulleys 28 below the tarpaulin guide roller 33. Thus, the stanchion rollers 28 and the tarpaulin guide roller 33 are at least partially juxtaposed. The same applies to the tarpaulin guide surface 34, which is offset inwardly against a plane E3 on the outside of the spar structure 11, in the direction of the stanchion carriage 17 and in the direction of the stanchion rollers 18. The tarpaulin guide roller 33 and the tarpaulin guide surface 34 are in the illustrated and So far preferred roof 3 flat, so not formed with a curved cross-section. In addition, the stanchion rollers 18 are provided together on the side of the stanchion slide 17 facing away from the tarpaulin guide roller 33 and the stanchion slide section 20 adjacent to the stanchion rollers 18.

In one embodiment, not shown, instead of the tarpaulin roller 33, a tarpaulin support may be provided, which can then be supported on the tarpaulin surface 4 in the form of a tarpaulin support surface. The tarpaulin does not roll off the spar structure in the absence of a corresponding roller. Rather, the tarpaulin support is supported on the tarpaulin support surface, or the tarpaulin support slides off when moving the tarpaulin on the tarpaulin support surface. If necessary, the tarpaulin support made of a plastic and if desired elastic.

Spriegelroller 35 are associated with the upper leg 13 of the spar structure 11 are provided, which are connected to transversely to the roof 3 extending bows 36. The mirrors 36 carry the tarpaulin of the roof 3 and can be moved over the Spriegelroller 35 along the spar structure 11. In this way, a so-called sliding roof is obtained. The Spriegelroller 35 are supported on two Spriegellaufrollen 37 on a Spriegellauffläche 38 of the spar structure. When moving the bows 36 and the tarpaulin 2 of the roof 3 along the spar structure, the baffles 37 roll on the baffle bearing surface 38. So that the bow 36 and the Spriegelroller 35 are not accidentally lifted off the spar structure 11, the Spriegelstützrollen 39 associated with the outside of the Spriegelroller 35 against against a support surface 40 from. Between the two Spriegellaufrollen 37 and the Spriegelstützrollen 39 is still a Spriegelführungsrolle 41 is provided which can roll on opposite Spriegelführungsflächen 42 to guide the displacement of the Spriegelrollers 35 along the spar structure 11.

In the illustrated and so far preferred roof 3, the Spriegelführungsflächen 42 and the tarpaulin guide surface 34 and parallel to the lateral leg 14 of the spar structure 11, perpendicular to the roof 3 and / or vertically aligned while the Spriegelellauffläche 38 and the support surface 37 parallel to the roof 3, parallel to the upper leg 13 of the spar structure 11 and / or aligned horizontally. In addition, the Spriegelellaufrollen 37, the Spriegelstützrollen 39 and the Spriegelführungsrolle 41 level treads. Correspondingly corresponding to the Spriegellauffläche 38, the support surface 40 and the Spriegelführungsflächen 42 are also flat. Incidentally, a plastic seal 43 is laterally fixed to the spar structure 11 for sealing the roof 3, which extends laterally partially over the tarpaulin roller 26 and the tarpaulin 4 down.

In the Fig. 4 a cross-section through the spar structure 11 is provided adjacent to the rear wall 8, which comprises a mounting profile 44 which is inserted into the associated end of the spar structure 11 in the longitudinal direction of the spar structure 11 and provided for connecting the spar structure 11 with the rear wall 8. The illustrated and insofar preferred mounting profile 44 is formed on the one hand flat and on the other hand elongated sheet metal component and is inserted into the receiving space 19 for the Runge pulleys 18. The mounting profile 44 has distributed over its longitudinal extent a plurality of threaded holes 45, are screwed into the bottom of screws 46 to form a screw 47 between the spar structure 11 and the rear wall 8. The mounting profile 44 is inserted with its right edge in a U-shaped receptacle 48 of the spar structure 11 and extends as the receptacle 48 further outward than defined by the tarpaulin guide surface 34 and perpendicular to the roof 3 extending plane E4. In this way, a large contact surface between the mounting profile 44 and the spar structure 11 is achieved, which extends through the contact surface 49 in the U-shaped receptacle 48 on one side of the slot 15 in the bottom of the spar structure 11 and the two contact surfaces 50,51 adjacent to the Runge tread 24 and on the other side of the slot 15 composed. The spar structure 11 is guided further outward below the tarpaulin guide face 34 with respect to the tarpaulin guide face 34 in order to create more space for receiving a wider mounting profile 44 inside the spar structure 11, in particular in the receiving space 19 for the idler rollers 18, transversely to the spar structure 11 can provide a larger contact area with the spar structure 11. Basically, the receiving space 19 for the Runge running rollers 18 below the tarpaulin guide surface 34 transverse to the spar structure 11 and parallel to the roof 3 be wider than at the level of the tarpaulin guide surface 34 to accommodate the mounting profile 44 in a suitable manner.

The end wall of the illustrated and so far preferred tarpaulin structure 1 is connected analogously to the rear wall 8 via a mounting profile 44 with the spar structure 11. Since the tarpaulin rollers 26 do not have to be moved to the corresponding end regions of the spar structure 11, the mounting profiles 44 provided there do not disrupt the opening and closing of the tarpaulin 2.
